Background technology
Traditional vehicle bracelet has safety strap, and belt installation is at the correct position of vehicle.When the passenger fastened one's safety belt, safety strap passed and hangs on the preposition, for example on three points, was terminated in the bracelet, and the tongue piece that is connected in its end is supported.As everyone knows, bracelet can improve passenger's safety under unexpected situation.
Buckle of safety belt should be able to discern the driver and/or whether the passenger has fastened safety strap.Buckle of safety belt generally includes mechanical switch, and for example micro-switch is used to cooperate tongue piece to move together.Therefore, micro-switch response tongue piece inserts and wherein opens or closes, thereby lights or extinguish the Warning light that is installed on the gauge panel, has driver and/or passenger not to fasten the safety belt with warning.
Buckle of safety belt can also comprise non-contact switch, and Hall element for example is to carry out for example self-checking function of the electronic control unit of ECU.When the passenger does not fasten the safety belt, non-contact switch detects the error state of vehicle to force to light all Warning lights on the gauge panel, can carry out simultaneously and the vehicle relevant proper operation of advancing, for example restricted speed, air bag are in the readiness of work, or the like, thereby improve the efficient of vehicle control.
But the structure of buckle of safety belt makes contact and/or non-contact switch be installed in separately or together wherein, the lock-out state or the unlock state of identification buckle of safety belt under situation about being separated from each other.This structure makes separated contact and non-contact switch be installed in its suitable position, mainly is the bottom surface of lower casing, opens and closes contact and/or non-contact switch thereby whether insert bracelet according to tongue piece in the predictive error interval.
For example, operate these with the cooperative dead bolt of tongue piece, pushing piece or moving-member in the bracelet and contact and/or non-contact switch by being installed in.The installation site that this means them is limited and the spacing that is installed separately is fixed.And this structure may cause switch fault owing to tongue piece misplugs in the bracelet.
For addressing these problems, at U.S. Patent Publication No. No.5, the employing to non-contact switch was disclosed in 960,523 (on October 5th, 1999), it relates to a kind of seat belt buckle sensors.Sensor is used for directly monitoring or monitors the appearance and the position of tongue piece by the activity of measuring dead bolt.For example, by on dead bolt, placing a small magnet and, can monitoring the whole show scope of dead bolt, comprise its moving and moving up and down in response to the parallel of belt force measuring magnetic-field intensity with the relatively-stationary appropriate location of buckle of safety belt.Sensor in the integrated circuit encapsulation is installed on the fixed position of dead bolt follower spring strut member, also comprises the guide plate of dead bolt.Thereby magnet moves to cooperate working sensor along dead bolt.
